Abstract: Some of the basic dosimetric properties of experimental and commercially available American, Japanese, French and Federal Republic of Germany silver-activated phosphate glasses which have either a different glass base, but similar silver content, or a constant glass base but different silver content, are compared under identical conditions, particularly (a) the kinetic behaviour (build-up and fading of the radiophotoluminescence, RPL) after high-intensity gamma exposure was studied under different conditions, such as storage at room and increased temperatures before and after "stabilization" by a short heat tteatment; and (b) the relative and absolute RPL spectra of the glasses were measured under different conditions (dose level, build-up, temperature treatment). On the basis of these results, a proper definition of the terms "pre-dose" and "sensitivity" of the RPL dosimeters and their relative significance is possible. The practical consequences, in particular thepossibilities of avoiding errors in RPL measurements immediately, or a very long time after exposure, or by using different readers, are discussed briefly.
